PA3 (PATRI) Solution of tritium sampling passive and smart.
PA3 a novel device to trap passively atmospheric tritium (HTO) representative of the monitored environment.
Developed and developed by the laboratory LS3E of IRSN, PA3 technology is patented.

During the picking process realized using PA3 the user is pro-active : it can monitor anytime in real-time the tritium sampling quality indicators.
Intelligence at user service
Équipé d’une technologie sans contact, PA3 est vecteur d’informations en transportant les données collectées sur le terrain. Le piège PA3, arrivant au laboratoire, est identifié et transmet les données utiles au calcul de l’activité volumique du tritium atmosphérique.
Advantages
- Compact geometry and reusable
- Continuous sampling from 1 day to 1 month
- Electrical autonomy
- Easily deployable
- Robust technology
- Not sensitive to weather conditions
The PA3 passive trap consists ofa tapered cartridge welcoming a molecular sieve (adsorbent material) which collected preferentially atmospheric tritium in proportion constant regardless of the relative humidity. Geometry has been designed to facilitate the transport of molecules from the air to the device of trapping through the property of molecular diffusivity of gas.
Un gradient de pression négative est entretenu entre une ouverture normée (définissant la période de prélèvement) et le média de piégeage réalisant le rôle de micro-pompe et adsorbant l’eau tritiée de manière linéaire et sans effet de saturation.
The principle of the PA3 technology allows samples of the weather of low activity without effect of dilution, as well as releases to strong activities.
Pre-filled cartridge (molecular tamis) and regeneratable after use.
